I asked a body shop about rolling the fender lip for me and they said it could change the shape of the fenders and wasn't a good idea. They have me worred.
The only problem you may have is the tire making contact with the INNER wheel well, near the bumpstop.
AS for your body shop it sounds like they want to "flair" your wheel well, rolling a quarter lip has ABSOLUTELY no affect on the general look of the car, it just gently bends the lip that points horizontally into the wheel well upwards, but like I said it won't need to be done, not on a 53 mm offset wheel.
